ALBERT G. STEVENS, OF CAPE MAY, NEW JERSEY.

NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 718,031, dated January 6, 1903.

Application filed March 29,1902. Serial No. 100.521. (No model.)

To all whom, t may conce/Ww Y Be it known that I, ALBERT G.. STEVENS, a

'i citizen of the United States, residing at Cape My invention relates to'a new and useful' improvementiu non-refilling bottles, and has for its object to so construct an attachment which may be placed in the neckof the bottle that although the contents of the bottle may be emptied out the bottle cannot be refilled. With these ends in View this invention con` sists in the details of` construction and combination of elements hereinafter set forth and then specilically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now'be described in detail, referring to the accompanying drawings, forming apart of this specification, in whieh Figure l is a vertical section of the neck of a bottle with my attachment applied thereto; Fig. 2, a similar viewto Fig. l, on a smaller scale, showing the parts inposition when the liquid is being poured from out of the bottle. In the drawings, A represents a casing which is adapted to be inserted in the neck of the bottle and held in place .by means of j the spring-bolts B, engaging internal annular grooves C, formed in the neck of the bottle. The lower end of the casing'is perforated, as indicated at D, in its center, and above this perforated portion is formed a cavity E, in which is located a plate F, which plate is perforated at F', the perforations being near the edge of the plate and not in line with the perforations D of the casing. This plate F is allowed a certain amount of vertical movement within the cavity E, and pins F" are provided to guide this plate in its movements. Any liquid flowing from the interior of the bottle through the perforations D will either raise the plate, or the plate will fall by gravity, as illustrated in Fig. 2, and allow the liquid to pass through the perforations F' into the cavity E; but if any liquid tries to enter the bottle from the opposite direction the plate F will instantly seat upon the lower portion tion G with the casing, and above this solid portion G is provided a movable portion H, the lower face of which is formed to fit the conical upper surface of the portion G. This movable portion H isprovided with an annular cavity H', which is connected with the chamber I above "the movable portion H by means of a series of perforations J. Pivoted to the upper surface of the movable portion H are a series of flap-valves J', adapted to normally close the perforations J. Above the chamber I is a solid portion K, formed with the easing, and from this solid portion a circular partition K' extends downward and passes through a circular slot formed in the movable portion H into the annular cavity H', and upon its lower end it is provided with disks K2, which, are adapted to close the perforations J when the movable portion H is in its lowest position.

L represents passages extending downward from the annular cavity H', and then upward through the portion H, and opens into the chamber I. The portion H is provided with fa central passage M, which passage is provcavity M, and is secured to the solid portion K, and extends a slight distance above the Vsolid portion K for the purpose hereinafter described. Upon this rod N are secured two cones O, which are adapted to seat against the tapering seats M',formed in the passage M.

The solid portion VK is provided with a series of perforations K3, formed through the same near its outer edge, and above this'solid portion K a cavity is provided in the casing, in which is located a weighted valve P. This valve is circular and is pivoted upon the central rod N, and one side of this valve is Weight- IOO 2 rmaosi ed, and the weighted side is provided with a right-angle passage P', the lower mouth of which is adapted to register with the series of perforations K3, and the other end of the passage opens into a cavity Q, provided in the valve P, and this end of the passage P is adapted to be normally closed by a flap-valve P2. Above the weight-valve P is the upper end ot the casing, which has a central aperture Q formed therethrough, and in this upper end of the casing is formed an annular chamber R, which has apertures R' extending from the annular chamber into the central aperture Q'. Perfex-ations S are formed, extending from the cavity in which the weighted valve rotates into the an nular chamber R. These perforations S are in such a position that some of them will always lie directly above the cavity Q in the weighted valve.

Itwill now be seen that if the bottle is turned at the proper angle for pouring out the liquid the liquid will pass through the perforations D in the lower end of the casing, and as the plate F will be removed from its seat the liquid will pass through the perforations F in the plate into the chamber E and from there through the openings G around the solid portion G, and the movable portion H will be moved from ott its seat either by the force of the liquid or its own weight, and the liquid will then pass upward through the central opening M and then downward through the passage L into the annular chamber H', out of the perforations J into the chamber I, then through one of the perfora` tions K3 into the right'angle passage P' of the weighted valve, from there into the cavity Q, through the perforations S into the annular chamber R, and then through the perforations R' into the aperture Q. It will be seen that by following this course of the liquid all ot' the valves are so arranged as to allow the liquid to ow outward; but in trying to force any liquid into the bottle all of the valves will operate in just the opposite direction and prevent the liquid from Iiowing in, no matter what position the bottle may be placed in.

Upon the conical seat of the solid portion G, I provide radial grooves G3, which will allow the liquid to enter part way between the solid portion G and movable portion H and help to force the movable portion I-I from ofi:` its seat. I also provide -such grooves upon the conical seats O, secured to the central rod N, for the same purpose.

Of course I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is l. In a non-relling bottle, a casing adapted to be inserted within the neck of the bottle, means for automatically locking said casing within the neck of the bottle, perforations formed through the lower end of the casing,

a plate arranged upon the interior of the casing and adapted to seat against the lower end, said plate provided with perforations out of register with the perforations through the lower end of the casing, a solid portion arranged above the movable plate, said solid portion having openings formed around its periphery, a movable portion arranged above the solid portion and adapted to seat upon the same, a series of annular cavities and passages formed in the movable portion, a series of valves also carried by the movable portion and adapted to allow the egress of liquid but prevent the ingress, a solid portion arranged above the movable portion, said solid portion provided with a series of openings around its outer edge, a weighted circular valve arranged above the solid portion, a right-angle passage formed in the weighted end of the valve, the lower end ot said passage adapted to be in register with the series of openings formed through the solid portion, the other end of said passage opening into a cavity formed in the weighted end of the valve, a iiap-valve adapted to close this end of the passage against the ingress of liquid,a central aperture formed through the upper end of the casing, an annular chamber formed in the upper end of the casing around the central aperture, the upper end of the casing provided with openings connecting the central aperture with the annular chamber and the annular chamber with the cavity formed in the weighted end of the valve, substantially as and for the purpose specified.

2. In anon-refilling bottle, a casing adapted to beinsertedin the neckof the bottle,means for automatically locking said casing within the neck, the lower end of the casing provided. with perforations D extending therethrough, aplate F arranged upon the interior of the casing and adapted to seat against the lower end, said plate being movable longitudinally of the neck of the bottle and provided with perforations F out of register with the perforations D, asolid portion G formed with the casing above the plate, an opening Dl formed around the outer edge of the solid portion, amovable portion H arranged above the solid portion and adapted to seat thereon, a central passage M formed through the movable portion, a stationary central rod secured to the casing, two conical valves secured to the central rod, conical seats formed in the central passage M adapted to seat upon the conical portions when the movable portion H is in its lowest position, a passage L formed in the movable portion extending from the upper end of the movable portion downward into the annular cavity H in the movable portion, nap-valves adapted to close the passage L against the ingress of liquid from the annular cavity H', a stationary circular partition K extending from above through the movable portion H into the annular cavity H', perforations J extending from the annular cavity through the upper end of the movable portion IOO IIO

H and arranged outside of the partition K', Hap-valves J' adapted to close the perforations J against the' ingress of liquid, a solid portion K arranged above the movable por-` the right-angle passage against the ingress of liquid, the upper end of the casing provided with the central aperture Q', and an annular cavity R surrounding the central cavity, the upper end of the casing also provided with apertures connecting the annular cavity with the central aperture, and perforations also connecting the annular cavity with the cavity in the weighted valve, substantially as and for the purpose specified.

3. In a non-refilling bottle,a casing adapted to be inserted in the neck of the bottle, means for locking said casing automatically in place, a circular Weighted valve arranged wi thin the casing, a passage formed in the weighted end of the valve extending from the lower face of the valve into a cavity Q formed in the weighted end of the valve, a iiap-valve P2 adapted to close the passage against the ingress of liquid, substantially as shown and described.

In testimony whereof I have hereunto affixed my signature in the presence of two sub- 35 scribing witnesses.
